Stewart Berg, the fan who was involved in a confrontation with Celtics forward Antoine Walker, filed an application for a complaint yesterday at Boston Municipal Court. As a result, a probable cause hearing will be held June 11.

Whether or not Walker chooses to speak, he is required to appear for the hearing. Walker spends much of the offseason in Chicago.

After the hearing, the clerk magistrate will decide if charges are warranted.

The incident occurred May 9 at the FleetCenter. Throughout Game 3 of the Eastern Conference semifinal series between the Celtics and New Jersey Nets, Berg heckled Walker, calling for Celtics coach Jim O'Brien to take Walker out of the game. Once Walker exited the contest late in the fourth quarter, he walked toward Berg and confronted him.
